Linux more命令 示例

分页显示文件/etc/services的内容

[root@rhel ～]# more /etc/services
# /etc/services:
# Id: services, v 1.482009/11/11 14:32:31 ovasik Exp
#
# Network services, Internet style
# IANA services version: last updated 2009-11-10
#
# Note that it is presently the policy of IANA to assign a single well-known
# port number for both TCP and UDP; hence, most entries here have two entries
# even if the protocol doesn't support UDP operations.
#Updated from RFC 1700, ''Assigned Numbers''(October 1994). Not all ports
# are included, only the more common ones.
#
# The latest IANA port assignments can be gotten from
#   http://www.iana.org/assignments/port-numbers
# The Well Known Ports are those from 0 through 1023.
# The Registered Ports are those from 1024 through 49151
# The Dynamic and/or Private Ports are those from 49152 through 65535
#
# Each line describes one service, and is of the form:
#
#service-name port/protocol [aliases...] [#comment]
tcpmux      1/tcp                      #TCP port service multiplexer
tcpmux      1/udp                     #TCP port service multiplexer
rje          5/tcp                      #Remote Job Entry
rje          5/udp                     #Remote Job Entry

从第20行开始显示/root/testfile文件的内容

[root@rhel ～]# more +20 /root/testfile

一次两行显示/etc/passwd文件的内容

[root@rhel ～]# more -2 /etc/passwd
root:x:0:0:root:/root:/bin/bash
